Abstract

Examines techniques that discover features in sets of pre-categorized documents, such that similar documents can be found on the WWW. Examines techniques which will classifiy training examples with high accuracy, then explains why this is not necessarily useful. Describes a method for extracting word clusters from the raw document features. Results show that the clustering technique is successful in discovering word groups in personal Web pages which can be used to find similar information on the WWW

Abstract

It is apparent that, despite the common reference to the World Wide Web as a "digital library", it lacks any of the organising features which would be expected from a library. The rate of growth of Web resources is such that they have grown, and continue to grow, beyond the ability of human intervention to catalogue them or control access to them. The software tools which have so far emerged to assist searching are inadequate for the task, but it is hoped that a development in standards will lead to documents being created with the "hooks" in place, which will facilitate their retrieval by tools yet to be developed. Dublin Core metadata appears to be the optimum such emergent standard, and its use is to be encouraged among Web authors.

Abstract

The Dublin Core is a 15 element set intended to facilitate discovery of electronic resources. Its characteristics are: simplicity, semantic interoperability, international consensus, flexibility, metadata modularity on the Web and a metadata architecture for the Web. The WWW Consortium is developing the Resource Description Framework to support different metadata needs. It will support 3 resource description models: embedded metadata, third party metadata, and view filter. Development continues into: refinement of elements, user education and application guides, metadata registries, tools and standardization. Includes a list of related Web sites and details of the core elements

Abstract

The main objective of the proposed high-level 'Visual Repository Definition Language' is to anbale advanced Web presentation of large amounts of exisitng heterogeneous information. Statements of the language serve to describe the desired structure of information repositories, which are composed of metadata entities encapsulating the original data. Such approach helps to to avoid the usual relocation and restructuring of data that occurs when providing Web access to it. The language has been designed to be useful even for inexperienced programmers. Its applicability is demonstrated by a real example, creating a repository of judicial opinions from publicly available raw data

Abstract

We propose an extension of a mediator architecture. This extension is oriented to ontology-driven data integration. In our architecture ontologies are not managed by an extemal component or service, but are integrated in the mediation layer. This approach implies rethinking the mediator design, but at the same time provides advantages from a database perspective. Some of these advantages include the application of optimization and evaluation techniques that use and combine information from all abstraction levels (physical schema, logical schema and semantic information defined by ontology). 1. Introduction Although the Web is probably the richest information repository in human history, users cannot specify what they want from it. Two major problems that arise in current search engines (Heflin, 2001) are: a) polysemy, when the same word is used with different meanings; b) synonymy, when two different words have the same meaning. Polysemy causes irrelevant information retrieval. On the other hand, synonymy produces lost of useful documents. The lack of a capability to understand the context of the words and the relationships among required terms, explains many of the lost and false results produced by search engines. The Semantic Web will bring structure to the meaningful content of Web pages, giving semantic relationships among terms and possibly avoiding the previous problems. Various proposals have appeared for meta-data representation and communication standards, and other services and tools that may eventually merge into the global Semantic Web (Berners-lee, 2001). Hopefully, in the next few years we will see the universal adoption of open standards for representation and sharing of meta-information. In this environment, software agents roaming from page to page can readily carry out sophisticated tasks for users (Berners-Lee, 2001). In this context, ontologies can be seen as metadata that represent semantic of data; providing a knowledge domain standard vocabulary, like DTDs and XML Schema do. If its pages were so structured, the Web could be seen as a heterogeneous collection of autonomous databases. This suggests that techniques developed in the Database area could be useful. Database research mainly deals with efficient storage and retrieval and with powerful query languages.

Abstract

Examines international efforts to promote metadata as a common, interactive resource description tool for the Internet. These efforts centre on the Dublin Core Element Set, but include qualifiers such as those promoted by the Canberra Qualifiers. The LoC Network Development and MARC Standards Office maintains the Dublin Core / MARC / GILS (Government Information Location Standards) crosswalk which maps the common and correlative elements of each system. Describes current international initiatives and issues. Describes the Nordic metadata project which is aiming to create the basic elements of a metadata production and utilization system based on the Dublin Core Metadata Element Set. Describes the WWW consortium efforts in this area

Abstract

We discuss the issues of resolving the information-retrieval problem in large digital collections through the identification and use of document genres. Explicit identification of genre seems particularly important for such collections because any search usually retrieves documents with a diversity of genres that are undifferentiated by obvious clues as to their identity. Also, because most genres are characterized by both form and purpose, identifying the genre of a document provides information as to the document's purpose and its fit to the user's situation, which can be otherwise difficult to assess. We begin by outlining the possible role of genre identification in the information-retrieval process. Our assumption is that genre identification would enhance searching, first because we know that topic alone is not enough to define an information problem and, second, because search results containing genre information would be more easily understandable. Next, we discuss how information professionals have traditionally tackled the issues of representing genre in settings where topical representation is the norm. Finally, we address the issues of studying the efficacy of identifying genre in large digital collections. Because genre is often an implicit notion, studying it in a systematic way presents many problems. We outline a research protocol that would provide guidance for identifying Web document genres, for observing how genre is used in searching and evaluating search results, and finally for representing and visualizing genres.

Abstract

Conceptual Knowledge Markup Language (CKML), an application of XML, is a new standard being promoted for the specification of online conceptual knowledge (Kent and Shrivastava, 1998). CKML follows the philosophy of Conceptual Knowledge Processing (Wille, 1982), a principled approach to knowledge representation and data analysis, which advocates the development of methodologies and techniques to support people in their rational thinking, judgement and actions. CKML was developed and is being used in the WAVE networked information discovery and retrieval system (Kent and Neuss, 1994) as a standard for the specification of conceptual knowledge

Abstract

This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

Abstract

Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

Abstract

The goal of the State Library of Queensland's Metadata Project is the deployment of metadata using the Dublin Core Metadata Element Set in the State Library' WWW Web pages. The deployment of metadata is expected to improve resource discovery by Internet users, through provision of index information (metadata) in State Library Web pages which is then available to search engines for indexing. The project is also an initial attempt to set standards for metadata deployment in queensland libraries Web pages

Abstract

The relationship between library catalogues and electronic resources differs from that between catalogues and physical materials, particularly with regard to cataloguing rules, which were originally designed to help users of card catalogues to find physical works on library shelves. However, these rules apply awkwardly to electronic resources because functionally different electronic works raise special cataloguinf issues. Discusses the problems of describing remote electronic resources in online catalogues with particular reference to the InterCat project: a nationwide experiment to create a database of Internet resources in MARC format, containing description, location and access information (including PURLs = Persitent URLs)). Concludes that descriptive information helps the user identify the works needed, but that it is practical to provide only minimal desriptive information for remote electronic resources in the catalogue record. To a limited extent, the access lost from reduced description can be replaced with new cataloguing techniques designed to stabilize the catalogue record

Abstract

Mit elektronischem Publizieren werden folgende Eigenschaften verbunden: »schnell, kostengünstig, weltweit«. Aber ist das aus Nutzersicht bzw. aus der Perspektive der Autoren ausreichend, um eine Online-Veröffentlichung dauerhaft zu nutzen und zuverlässig zu zitieren? Ein Mechanismus, mit dem netzbasierte Publikationen eindeutig gekennzeichnet werden und jederzeit auffindbar sind, wird durch flüchtige Uniform Resource Locator (URLs) nicht bereitgestellt. Eine Lösung bieten Persistent Identifiers (Pls), wie z. B. Uniform Resource Names (URN)". Damit die Anwendung eines persistenten Adressierungsschemas wie den URNs langfristig gewährleistet werden kann, muss eine Infrastruktur mit einer institutionellen Unterstützung geschaffen werden. Ein wesentlicher Aspekt in diesem Kontext ist die Langzeitarchivierung der digitalen Objekte. Die Darstellung und Erläuterung der Schnittstellen zwischen Langzeitarchivierung und Pls sowie der damit verbundenen Aktivitäten und Ergebnisse des EPICUR-Projektes war Gegenstand des Vortrages von Kathrin Schroeder auf dem diesjährigen z. Bibliothekskongress in Leipzig im Rahmen des Workshops »Technische Aspekte der Langzeitarchivierung«". Es besteht ein enger Zusammenhang zwischen den Bereichen Pls (standortunabhängige, eindeutige Bezeichner für digitale Objekte) und Langzeitarchivierung (Maßnahmen, die dazu dienen, digitale Objekte für die Nachwelt dauerhaft zu erhalten): Pls werden als stabiler Zugriffsmechanismus für digitale Objekte verwendet, die in einem Depotsystem archiviert werden. Ein Depotsystem ist ein »( ...) Archiv für digitale Objekte, in dem Menschen und Systeme als 'Organisation' mit der Aufgabenstellung zusammenwirken, Informationen zu erhalten und einer definierten Nutzerschaft verfügbar zu machen.« Dazu gehören im erweiterten Sinne auch eine Infrastruktur vor der Eingangsschnittstelle des Depotsystems, die zum Transfer digitaler Objekte von den Produzenten in das Archiv dient, und die Infrastruktur der Endnutzer-Umgebungen hinter der Auslieferungsschnittstelle des Depotsystems, in denen die digitalen Objekte benutzt werden sollen. In diesem Umfeld werden Pls in folgenden Bereichen angewendet: - Metadaten, - Datenaustauschformate, - Automatisierte Lieferungen von Objekten in ein Archivsystem, - Depotsystem und - Nutzung von Pls als stabiler Zugriffsmechanismus auf ein Objekt als wichtigster Aspekt für den Endnutzer (Wissenschaftler und Autoren). Im Folgenden werden zu den einzelnen Bereichen die Ergebnisse des EPICUR-Projektes und die Aktivitäten Der Deutschen Bibliothek diskutiert.

Content

The PICS, an initiative of W3C, is a technology that supports the association of descriptive labels with Web resources. By providing a single common transport syntax for metadata, PICS will support the growth of metadata systems (including library cataloguing) that are interoperable and widely supported in Web information systems. Within the PICS framework, a great diversity of resource description models can be implemented, from simple rating schemes to complex data content standards

Abstract

Subject oriented information sources on the Internet remain relativley unstructured despite attempts at indexing them and despite the use of search engines to index sources in a collective database and to retrieve relevant information sources. Describes the rationale for developing a means to capture and structure Internet resources for scientific research use in a clearinghouse, and methods for retrieval, information filtering, and structuring subject orientated information sources from the Internet for specific user groups. Discusses the issues of design, maintenance, implementation of metadata, and obtaining use feedback. Cooperation among several institutions involved in the German national subject special collections (SSG) library support programme of the DFG have led to recommendations to expand this programme to include coordination of collective Internet subject information sites. In addition to the compilation of subject oriented information sites on the Internet by library and information staff, connection to other value added services serve to make processes of information searching, retrieval, acquisition, and evaluation more effective for researchers

Abstract

Discusses how information will be found in digital libraries of the future. Suggests that a metadata approach to cataloguing will prevail, whereby the content of the data will be analysed at source, rather than on receipt by an intermediary, altering the role of the cataloguer, who will be required to evaluate as well as classify and index. Web site administrators may have to provide site metadata for use by global indexers; provides some examples of projects aimed at developing standards and assisting information providers in creating descriptive metadata

Abstract

Describes the structure of metadata formats with particular reference to the taxonomy of data formats set out by the BIBLINK report of the UK Office for Library and Information Networking and based on their underlying complexity. Referes to 3 main types of metadata: Dublin Core; MARC and Federal Geographic Data Committee (FGDC). Provides practical examples of the actual codings used, illustrated with reference to the Dublin Core, Marc and FGDC elements in selected Web sites. Ends with a glossary and a list of Web sites containing background information on metadata, such as the IAMSLIC metadata homepage

Abstract

Comments on the value of abstracts or summary notes to information available online via the Internet and WWW and concludes that automated abstracting techniques would be highly useful if routinely applied to cataloguing or metadata for Internet documents and documents in other databases. Information seekers need external summary information to assess content and value of retrieved documents. Examines traditional models for writers, in library audiovisual cataloguing, periodical databases and archival work, along with innovative new model databases featuring robust cataloguing summaries. Notes recent developments in automated techniques, computational research, and machine summarization of digital images. Recommendations are made for future designers of cataloguing and metadata standards
